S. M. Stelmack - The Femme Vendettas (#1-2)

Fox Hunt (The Femme Vendettas #1)
Brian Chanse, self-diagnosed adrenaline junkie and all-round good guy, is driving through a freak rainstorm in New Mexico when he takes pity on a hitch-hiker. Little does he know that his passenger has loads more problems than mild hypothermia. It turns out that ex-cat burglar Delta Fox is running for her life. Why and from whom, she doesn’t know, but the answers lie in her old stomping grounds in L.A. After Brian outmanoeuvres the Yakuza in a high-speed car chase, Delta appreciates his talents but resists his offers of help. When the Yakuza threatens his staff, however, Brian insists they team up. So begins their partnership into the L.A. underworld, into a twisted place of murder and seduction, betrayal and revenge. Between her stealth skills, his stunts and their compulsion to watch over each other, they just might survive the hunt.

Gina Takes Bangkok (The Femme Vendettas #2)
The last heir of the Zaffini crime family, nothing scares Gina. Not car crashes. Not death threats. Not assassins. Not even Kannon Takahama, the legendary gunman her father charged with avenging the slaughter of his best friend’s family. Set loose on the shifting underworld of Bangkok, the two must outmanoeuvre a monstrous clan from the nightmare jungles of Cambodia, all the while negotiating the minefield of their mutual attraction. There’s a chance they could win the first battle. As for the second, well, Gina intends total surrender from the muscled hitman. After all, she can’t be frightened, and there’s nothing more scary than love.
